Abstract:
An underwater propulsion device is disclosed comprising two sleeves for fitting around each of a user's lower legs, with each sleeve mounting a propulsion unit, and the sleeves being connectable by a bar between them during underwater operation of the device by the user.
Abstract:
An electricity generating system includes a first electrode located at a first location in a body of salt water and a second electrode located at a second location in the body of salt water. The first and second electrodes may be of the same or different materials and are designed to present a large surface area to the body of water. A direct current flows between the two electrodes which is a function of the salinity of the water and the composition of the electrodes. The direct current is applied to the input port of a converting device which may be any suitable power inverter which can produce a output AC voltage corresponding to the direct current or a DC to DC converter to produce an output DC voltage corresponding to the direct current.
Abstract:
The invention relates to a vessel for operating on a body of water comprising: a non-planing hull having a waterline and a longitudinal direction with a forward portion, an aft portion, and a central portion, the hull being configured to have the aft portion with a smaller water displacement relative to a water displacement at the central portion; and an aft foil affixed to the aft hull portion with one or more connecting members, and below the surface of the water, and spaced from the hull, the aft foil having a span, a chord, and a leading edge and a trailing edge relative to a forward direction, wherein the leading edge of the aft foil is tilted at a downward angle relative to the horizontal, wherein the aft foil has a chord and profile in longitudinal cross section, with a configuration to provide a lifting force, the tilt angle of the chord of the aft foil being measured with respect to the horizontal, and wherein the aft foil is oriented to provide a continuous, upward, forwardly directed component of the lifting force.

Abstract:
An off shore, stable floating system that uses several wind turbines for power output and hydrogen production by electrolyzing water while being able to easily and safely relocate for better wind conditions with on board maintenance of the equipment. The produced hydrogen gas is either compressed and stored in strong tanks or liquefied and placed into insulated tanks for quick helicopter transfer to shore, or transferred to surface ships with insulated containers.
Abstract:
The invention comprises a scalable, configurable “propulsor” system. A propulsor system is an assembly of individual propulsors that act in concert to form a substantially continuous control surface that undulates in a working fluid. Each propulsor is driven and configured by computer-controlled actuators so that the control surface undulates in various wave forms. Optional actuators that may refine the surface shape include an “orientation” actuator that drives rotation about the propulsor's longitudinal axis, and a “geometry” actuator that controls each propulsor's geometric configuration.
Abstract:
Passenger boats are accelerated along a submerged guide rail structure that is arranged in various closed loop courses, including nullFigure-Eight,null hour-glass, serpentine and oval patterns, as well as linear guide track structures that extend in parallel between a launch station and a return station. A dual nullFigure-Eightnull watercourse includes a simulated jump ramp and an underground tunnel arrangement. The launching and operating speed of each boat relative to the other is controlled so that the boats approach and pass in close proximity to each other and then recede from each other as they travel in opposite directions along adjacent guide track sections, and in passing, project water spray onto each other.
Abstract:
Passenger boats are mounted on an undercarriage assembly that includes rail-mounted centering wheels. The passenger boats are accelerated by linear induction drive motors mounted on a guide rail structure. Thrust is applied to the racing boats by magnetically conductive reaction plates that are attached to the undercarriage assembly and are movable through linear flux slots formed in the induction stators of the linear induction motors. The submerged guide track structure is arranged in various closed loop courses, including “Figure-Eight,” an hour-glass, serpentine and oval patterns, as well as parallel guide track structures that extend between a launch station and a return station. A dual “Figure-Eight” watercourse includes a simulated jump ramp and an underground tunnel arrangement. In the continuous loop guide structure, two or more boats are launched and separation is maintained by a safety block arrangement.
Abstract:
An actuating device for submarine vehicles in which power to control the vehicle is provided by apparatus responsive to the surrounding water pressure. At least one control cylinder, coupled to a wheel of the vehicle by a gear system, and at least one operating cylinder, coupled to a valve by a piston rod, are fluidly coupled together by a plurality of hose or pipe lines which selectively admit ocean-water surrounding the vehicle to the operating and control cylinders to control movement of the vehicle.
